I am using a Zenith HERO PC G31 desktop. This desktop has Intel Pentium Processor E5200 and an Intel G31 Motherboard. It has a 2GB Memory along with 320 Gb hard drive. I am using Genuine Windows 7 Professional operating system. The problem is that my desktop is attacked by a malicious program which I am unaware of to terminate. The anti virus alert message indentifies it as Win32/Autorun.gen!inf. Is it a virus or worm or trojan?
